Abstract (en)
[origin: EP0488284A2] A radiation thermometer is provided at a pointed end thereof with an elastic infrared radiation member (1), which has a sectional shape convex toward the side of an object (3) to be measured and at least a thin film portion (1a) crossing an optical axis (P). By said member (1) an air tight room (4) is formed such that an internal pressure within said air tight room (4) may be higher than a pressure of the open air, so that the thin film portion (1a) can be surely adhered to the surface (S) of the object (3) to be measured and thus the temperature of the object (3) can be measured with high accuracy even in the case where the minimum measurable spot is large. <IMAGE>
